LONDON — King Charles III led the nation Sunday in a two-minute silence in remembrance of fallen service personnel in central London as the Princess of Wales looked on, a further sign the royal family is slowly returning to normal at the end of a year in which two of the most popular royals were sidelined by cancer.

When she announced she had finished chemotherapy in September, Kensington Palace only confirmed two engagements for the Princess for the rest of the year: today's service, and her annual Christmas Carol service at Westminster Abbey in December. No date has been announced yet for the Christmas event.
